2008 peterbilt 388

Hi guys I’ve got a 2008 peterbilt 388 with a ism Cummins. Was driving the other day when all of a sudden my all my gauges stopped working. They all got stuck half way digital gauge shut off. Checked all the fuses and relays all were good. Getting 12v to the cluster from power wire. I’m lost. Wiggles the harness back and forth nothing happens. What could this be. Only getting power at the power wire. No where else on the harness. Any advice or point me in the right direction would be appreciated. Thanks

 

I also replaced the cluster with another one out of a known good truck to see. Still nothing
